The process you describe sounds like it could work. Do you get any particular error when you use scheme_eval_compiled_multi() on the result of scheme_compile()?
Although it depends on the application, I would probably take a slightly different approach: Make all scripts modules, and write a glue module that uses the FFI to pull functions out of the host program (instead of having the embedding program push bindings into a Racket environment). The embedding program would export (at the DLL) functions for the glue module, and it would load scripts as module. Then, even if you run a script module from source, it is compiled once as the module is declared; each call into the script becomes more like calling a function instead of `eval`ing an S-expression.
